Collection: Biologique Recherche Masks

Frequently asked questions

• How often should I use a face mask?

  It depends on your skin. For oily or acne-prone skin, mask two to three times a week. For dry or dehydrated skin, start with once or twice a week and adjust from there. For sensitive or reactive skin, once a week with a gentle, barrier-supporting mask is usually enough. For anti-aging or maintenance, once or twice a week is generally right.

• How do I use a Biologique Recherche mask at home?

  Cleanse your skin, then apply Lotion P50. It gently exfoliates and adjusts your skin's pH so the mask can work more effectively. Apply the mask to your face, neck and décolleté, following the timing on the product page. Afterward, continue with your serums and moisturizer.

• Do I rinse a face mask off or leave it on?

  It depends on the mask. Some are rinse-off treatments, while others, like certain deeply hydrating masks, can be left on overnight. Follow the directions for your specific mask, and ask us if you're unsure.

• Can I use more than one Biologique Recherche mask at a time?

  Yes. Biologique Recherche masks are designed to be layered and combined. For example, Masque VIP O2 with Masque Vivant calms and clarifies at the same time, Masque PIGM 400 with Masque Biofixine targets pigmentation and aging in one session, and Masque VIP O2 with Masque Visolastine+ delivers intensive hydration and oxygenation.

• Do I need several Biologique Recherche masks for different skin concerns?

  No. You don't need a collection, you need the right one. A single mask used consistently will do more for your skin than several used occasionally. If you have two ongoing concerns, start with the mask for your main one and use it regularly for a few months before adding another.

• Which Biologique Recherche mask is best for sensitive skin?

  Masque Biosensible and Toleskin M are gentle, barrier-supporting options for sensitive or reactive skin. Start with once a week and let your skin guide how often you use it. If your skin is very reactive, book a consultation so we can recommend the best option for you.

• Which Biologique Recherche mask is best for oily or acne-prone skin?

  Masque Vivant is our go-to for oily and congested skin. Used two to three times a week, it helps keep oil balanced and congestion from building. Masque Bain de Plantes is another option that helps regulate oil and purify pores without drying the skin. Learn more in our Masque Vivant guide.

• How should I store my Biologique Recherche face mask?

  Keep your mask in a cool, dry place away from direct sunlight and heat, and close the lid or cap tightly after each use. Refrigeration isn't required, but some masks feel wonderfully cooling when kept in the fridge. Once opened, most Biologique Recherche products should be used within 3 to 12 months, depending on the product. Check the open-jar symbol on the packaging for the exact timeframe.
